PROBLEM TO BE SOLVED: To provide magnetic particle inspection method and device for performing an inspection test without restrictions in time and using a simple method, and for storing and recording the inspection result over a long time. SOLUTION: The observation surface of a magnetic sheet 19, where a sheet at least at an observation surface side, is formed by a transparent material, the area between the sheet at the observation surface side and that at a counter observation surface side is divided into a number of small chamber, and a magnetic particle 24 is dispersed into a dispersion medium 23 containing a thermosetting resin for sealing is brought into contact with or is pressed, and adhered to the flaw detection surface of a material whose flaw is to be detected. Then, the magnetic sheet is separated from the material whose flaw is to be detected, and heat is applied to the magnetic sheet 19, thus causing the dispersion medium 23 to be cured and fixing a magnetic particle pattern drawn on the side of the observation surface side.
